Fig. 8: Robustness of the inflation inequality to experimental noise.
From: Experimental nonclassicality in a causal network without assuming freedom of choice
In this plot, we show the achieved value for the inequality from inflation technique, as function of the two-fold coincidence window w1. As expected, since this increases uncorrelated 2-fold events, the measured correlations become “local" for large enough windows. The leftmost point corresponds to the result reported in subsection “Bounding measurement dependence and violating an entropic inequality for the triangle network", i.e., a window w1 ~ 4.1 ns, the plotted error bars are calculated through Monte Carlo technique assuming Poissonian statistics and are smaller than the size of the points. The blue shadowed region \({{{{{{{\mathcal{L}}}}}}}}\) indicates the values obtainable by a classical causal model.
